Stats page gone totally wierd

So - across all my blogs today (and yesterday) I cannot make out the statistics
I can get to the page
I can sweep the mouse over where there USED to be the bar chart graph thing to see the figures for weekly/monthly/daily hits or whatever....
The past two days - moving the mouse over that areas makes the number come up (I have to guess where the columns are tho)
But the actual bar bits have totally disappeared. I'm left with grey and white wide stripes where the graph used to be.

This has happened with my stats page too. It's probably a glitch. The problem is, it's a glitch that won't go away. I know wordpress.com has been doing some work with the stats page, but I'm not sure if that affects anything... Hope it gets fixed.
